| This file must be translated to C and modified to build everywhere. |
| |
| Run flex like this: |
| |
| flex --prefix=cmCommandArgument_yy --header-file=cmCommandArgumentLexer.h -ocmCommandArgumentLexer.cxx cmCommandArgumentLexer.in.l |
| |
| Modify cmCommandArgumentLexer.cxx: |
| - remove TABs |
| - remove "yyscanner" argument from these methods: |
| yy_fatal_error, yyalloc, yyrealloc, yyfree |
| - remove all YY_BREAK lines occurring right after return statements |
| - change while ( 1 ) to for(;;) |
| |
| Modify cmCommandArgumentLexer.h: |
| - remove TABs |
| - remove the yy_init_globals function |
| - remove the block that includes unistd.h |
| - remove #line directives (avoids bogus warning on old Sun) |
